JLinkZReader, a software program used for reading and writing flash ROM data directly from and to vehicle Engine Control Units (ECUs).

Key Features Explained:
- Primary Function: It is a tool for reading and writing the internal data (CPU flash ROM data) of automotive ECUs.
- Supported Processors: The program specifically works with a range of microcontrollers commonly used in automotive ECUs, including:
- TMS570LS11xx series (e.g., TMS570LS1113, TMS570LS1114)
- TMS570LS04xx series
- S32K142 (from NXP)
- TMS570LS31xx series (which includes the TMS570LS3135 from the previous text)
- TMS470R1A256
- Freeware for TMS570LS11xx: A significant point is that the program is completely free when used for reading data from the TMS570LS11xx family of processors.
